Well, System properties are not the same as OS environment properties. If you
want an OS environment property to exist in the JVM, you will have to set it
via the -D parameter on the command line, such as (on windows)....
java -Dlog.dir=%LOG_DIR% MyClass
Then, in your log4j.xml file...
<param name="File"
value="${log.dir}/jboss/${jboss.server.name}/server.log"/>
